The Lowdown
Alright folks, Rusty here. Let’s be straight with you. This is a tough one for the Kohala Lighthouse area. The whole 16-day window looks like a write-off for a decent paddle surf. Every single day, from Monday the 3rd of August right through to Tuesday the 18th of August, is a mess of cross-shore and cross-onshore winds, blowing anywhere from 9 mph right up to a solid 28 mph. The swell is there, but it’s all wind-affected, chopped up, and just plain ugly. We’re talking about a real gap in the quality with no standout sessions at all.
The first few days, Monday the 3rd and Tuesday the 4th, have a bit of energy – combined swell energy around 478 (moderate) on Monday and 534 (moderate) on Tuesday. But the wind is ruining it. The water temp is sitting at 80°, which is pretty normal for this time of year, but you won’t care about that when you’re getting blown off your board.
By Wednesday the 5th and Thursday the 6th, the energy drops into the 100s (weak to moderate), and the period plummets to a short, snappy 5 to 9 seconds. It’s just a lumpy, cross-chop mess. For the rest of the first week and into the second, the swell bumps up again, hitting 8 ft on Sunday the 9th with strong energy (613), and then again around 7 ft on the 15th with even stronger energy (673). But it’s all cross-wind, onshore wind, or just a full-on cross-chop. The period is short to mid-range (5 to 8 seconds), so there’s no real power or shape to it.
Honestly, the only thing that setup looks halfway decent for is kite surfing, not paddle surfing. The wind is strong and consistent, and the swell is big enough to get a ride, but the conditions are just too rough for a surfboard. There are no good surf options in this 16-day window. It’s a blank run, and it’s a long one. Hopefully, the forecasts change, but for now, leave the boards at home.

Information about the Kohala Lighthouse Surf forecast
The above surf forecast table for Kohala Lighthouse provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kohala Lighthouse can be found by selecting the local surf guide option on the grey menu. Our Kohala Lighthouse surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kohala Lighthouse) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kohala Lighthouse may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
